Setup, Compatibility & Care
Before installation, ensure the vehicle's hub surface is clean and free of rust or debris to allow for a flush mount. The S90-1-08-003 is a System 1 spacer, meaning it is designed to seat precisely against the factory hub. Always verify that your current lug bolts provide sufficient thread engagement depth; in many cases, moving to a thicker spacer necessitates the purchase of longer, high-strength wheel bolts. For maintenance, check the torque on your wheel bolts periodically, especially after track days or frequent spirited driving. If you notice any signs of oxidation or wear, inspect the mating surfaces immediately.
